The short version
NeuroReader has no user account, sign-up, analytics, or advertising profile. The app may store presentation settings and optional, anonymous reading metrics in your browser's local storage. The browser extension may store readings you explicitly save on your device, and its presentation settings may use your browser's built-in sync when that feature is enabled. These local settings and readings are not sent to NeuroReader.
Nothing leaves your browser
Every transformation happens locally, on your device, using the JavaScript that ships with this page. The text you paste is never sent to a NeuroReader server and is not included in metrics. The web app does not save pasted text unless you explicitly press Save current reading in Reading settings. Saved web readings remain in this browser's local storage and can be deleted individually or all at once. The optional Read next queue stores only saved-reading IDs and their order in that same browser storage; it is not included in metrics or sent anywhere. Exporting saved readings creates a JSON file on your device containing the text you chose to save; it is not uploaded by NeuroReader. Saved extension readings remain in the extension's local storage and can be deleted from its popup.
No accounts, no tracking
- No cookies, analytics, tracking pixels, or fingerprinting are used by NeuroReader.
- No logins. NeuroReader does not know who you are or what you read.
- Optional local research metrics contain counts and settings, not your words, identity, or URLs; you can export or delete them in Reading settings.
- The app works fully offline after its static files load — you can save it and use it with no connection.
What about ads?
NeuroReader may show a single banner advertisement at the very bottom of the page. Ads never appear over the text you are reading — that is a vow, not a preference. The optional support button is provided by Buy Me a Coffee and may make a request to that service; NeuroReader does not send your reading text with it. The public README also offers optional GitHub Sponsors and Buy Me a Coffee links. Those links are user-initiated and lead to independent third-party services under their own privacy policies. The browser extension popup also contains a static “Your ad here” placeholder and a Buy Me a Coffee link. The placeholder loads no advertising code; the link opens only after you click it. NeuroReader does not attach page text, saved readings, or report contents to any support link. Any future advertising or third-party service will be named here before it is added.
Your text is yours
The text you paste into NeuroReader belongs to you. We never see it, never transmit it, and never share it. If you explicitly save a reading, it stays in your browser until you delete it. Transformations happen in milliseconds, entirely on your device.
Changes to this policy
If anything here ever changes, this page will be updated first, in plain language, and the changelog will say so. NeuroReader is built in public — the whole project history is open for anyone to read.
